Our research found that the Royal Navy lost 24 warships sunk or heavily damaged in October 1780, which must have affected Britain's ability to fight in the months before the surrender at Yorktown.
The Royal Navy was stretched to the breaking point in the later years of the American Revolution. At the same time as thirteen of Britain's colonies fought for independence, it was waging a worldwide war against the French, Spanish, and Dutch powers. The Royal Navy was called upon to defend the home islands in the English Channel and North Sea, and preserve territories of the Empire in the Caribbean, India, and elsewhere.
The French blockade of Gen. Cornwallis's army at Yorktown was crucial in the ultimate victory by the Americans and French. That blockade was made possible by the Comte de Grasse's victory in the Battle of the Chesapeake on September 5, in which the French held off a smaller British fleet trying to rescue Gen. Cornwallis.
But surprisingly, historians have not asked a crucial question. Would the outcome of that crucial battle been different if the French had not outnumbered the British by 26 ships to 19? What if the British had not lost 15 warships sunk a few months earlier in the hurricane season of 1780, the worst in recorded history?
In doing supporting research for Eric Jay Dolin's important essay, "Did Hurricanes Save America?," we were not able to find any histories of the period which provided answers. We couldn't even find a definitive list of British ships lost. In fact, all available lists of the losses in 1780 turned out to be incomplete.
So to create a list, we consulted original records of losses with Lloyds of London, the Annual Register published in 1781 with details of naval actions of the previous year, and Ships of the Royal Navy, by J.J. Colledge and Ben Warlow.

He had distinguished himself in the French & Indian War, and later in Parliament, where he warned that ''our present naval force was by no means adequate to the execution of our professed intentions.''
